III. Material Application Scenarios

1. 304: a general economical option, suitable for conventional working conditions without strong corrosion, such as clean water and ventilation systems;

2. 316L: molybdenum-containing low-carbon stainless steel, resistant to chloride ions and salt spray corrosion, preferred for chemical engineering and coastal projects;

3. 321: titanium-stabilized stainless steel with high-temperature resistance, suitable for high-temperature steam and heat exchange pipeline systems;

4. 2205 duplex stainless steel: high strength and strong corrosion resistance, suitable for seawater and heavily acid-alkali corrosive working conditions.

IV. Product Advantages

The solid flat-plate integral structure provides extremely strong medium isolation and sealing performance. The bolt holes are compatible with corresponding standard flanges, making disassembly, assembly, and replacement convenient. The sealing face is precision-machined and provides leak-free performance when used with gaskets. The stainless steel base material is rust-proof and corrosion-resistant, making it suitable for long-term use in clean, corrosive, high-temperature, and complex industrial environments.
